Abstract
The utility model relates to a tar and exhaust gas treating device which comprises a tar distilling main tower, a cooler and a gas-liquid separator which are in pipe connection with the main tower in sequence, and a liquid-ring vacuum pump. The liquid-ring vacuum pump is in pipe connection with the gas-liquid separator and is connected with a blower, and the blower is also in pipe connection with a water seal tank and a heating furnace in sequence. The utility model can greatly reduce the maintenance expense and the workload of equipment, effectively separate gases and farthest avoid environment pollution.
Description
Technical field
The utility model relates to a kind of Tar Exhaust Treatment Device.
Background technology
As shown in Figure 1, be the structural representation of Tar Exhaust Treatment Device of the prior art; Tar distillation in distillation king-tower 11 ', cat head produces a large amount of incoagulable gas, and reciprocating vacuum pump 14 ' provides power, and these gases are in time taken away, makes the cat head of king-tower 11 ' keep certain vacuum.Incoagulable gas cools off and solidifies through cooler 12 ', and a part forms liquid substance, and a part still keeps gaseous state, and separates at gas-liquid separator 13 '.The material that is left gaseous state is extracted out through reciprocating vacuum pump 14 ', discharges from the outlet of this reciprocating vacuum pump 14 ' then, owing to unavoidably can have H in the gas

2Deng impurity, environment is polluted.
From the above description as can be seen, reciprocating vacuum pump 14 ' plays key effect in the processing procedure of whole tar tail gas.Because it is higher from the incoagulable gas temperature that distillation king-tower 11 ' is extracted out, after subcooler 12 ' cooling, some composition condensation is separated out, and makes the piston, terminal valve etc. of vavuum pump 14 ' locate often to have stickum, influences the operate as normal of vavuum pump 14 '.When serious, parts damages such as piston, terminal valve be can make, often cleaning piston, terminal valve needed.Especially in summer, when autumn, equitemperature was higher, maintenance workload was very big, has influenced ordinary production.
Summary of the invention
The purpose of this utility model is to propose a kind of Tar Exhaust Treatment Device, and it can reduce the maintenance cost and the workload of equipment greatly, and divided gas flow effectively, and can farthest avoid environmental pollution.
For achieving the above object, the technical scheme that the utility model provides is: a kind of Tar Exhaust Treatment Device is provided, it comprises the tar distillation king-tower, the cooler that is connected with this king-tower pipeline successively, gas-liquid separator, characteristics are also to comprise a liquid-ring vacuum pump, this liquid-ring vacuum pump pipeline connects this gas-liquid separator, and connects a blower fan;
Described blower fan also successively pipeline connect a water sealed tank and a heating furnace.
Tar distills in the distillation king-tower, and cat head produces a large amount of incoagulable gas, and liquid-ring vacuum pump provides power, and these gases are in time taken away, makes distillation king-tower cat head keep certain vacuum.Incoagulable gas cools off and solidifies through cooler, and a part of gas cooled becomes liquid form, and a part of gas still is left gas form.The object of gas, two kinds of forms of liquid separates in gas-liquid separator, and gas is extracted out through liquid-ring vacuum pump.Wherein, can be melted into the gaseous matter of liquid in the vavuum pump by the liquids recovery in the vavuum pump.The gaseous matter that is not melted into liquid in the vavuum pump is discharged by blower fan, has so not only reduced the phenomenon of impurity bonding or obstruction vavuum pump piston, terminal valve, reduces maintenance capacity and maintenance cost, has also reduced pollution level.
Further, blower fan also successively pipeline connect water sealed tank and heating furnace, after the gaseous matter that is not melted into liquid in the vavuum pump is discharged by blower fan, enter water sealed tank, and enter the heating furnace burning, like this, just avoided the generation of polluting.
Description of drawings
Fig. 1 is the structural representation of Tar Exhaust Treatment Device of the prior art;
Fig. 2 is the structural representation of the utility model Tar Exhaust Treatment Device.
The specific embodiment
Following according to Fig. 2, a better embodiment of the present utility model is described.
As shown in Figure 2, be the structural representation of the utility model Tar Exhaust Treatment Device 1.It comprises tar distillation king-tower 11, and with its cooler 12 of being connected of pipeline successively, gas-liquid separator 13 also comprises liquid-ring vacuum pump 14, and these liquid-ring vacuum pump 14 pipelines connect this gas-liquid separator 13, and connect blower fan 15; Blower fan 15 also successively pipeline connect water sealed tank 16 and heating furnace 17.
Tar distillation in distillation king-tower 11, cat head produces a large amount of incoagulable gas, and liquid-ring vacuum pump 14 provides power, and these gases are in time taken away, makes the cat head of distillation king-tower 11 keep certain vacuum.Incoagulable gas cools off and solidifies through cooler 12, and a part of gas cooled becomes liquid form, and a part of gas still is left gas form.The object of gas, two kinds of forms of liquid separates in gas-liquid separator 13, and gas is extracted out through liquid-ring vacuum pump 14.Wherein, can be melted into the gaseous matter of liquid in the vavuum pump 14 by the liquids recovery in the vavuum pump 14.The gaseous matter that is not melted into liquid in the vavuum pump 14 is discharged by blower fan 15, has so not only reduced the phenomenon of impurity bonding or obstruction vavuum pump 14 pistons, terminal valve, reduces maintenance capacity and maintenance cost, has also reduced pollution level.
Further, blower fan 15 also successively pipeline connect water sealed tank 16 and heating furnace 17, after the gaseous matter of liquid is discharged by blower fan 15 when not being melted into vavuum pump 14 in, enter water sealed tank 16, and enter heating furnace 17 and burn, like this, can farthest avoid the generation of polluting.
